Investigating of antibiotic resistance in bacteria isolated from the blood of covid-19 patients admitted to the special corona ward of Kosar Semnan Hospital

Background: More than two years have passed since the epidemic of Covid-19, this disease is still a global crisis. Antibiotic resistance is a global challenge. Therefore, this study aimed to identify and determine the antibiotic resistance of bacteria isolated in the blood samples of patients with Covid-19 hospitalized in the special corona ward of Kosar Semnan Hospital during 2020-2021. Materials and Methods: The current study is a retrospective cross-sectional descriptive study that was conducted in Semnan. In this study, 22 blood samples with positive bacterial cultures related to patients with Covid-19 were included in the study. The average age of the studied patients was 74.09. 13 patients were male and 9 were female. Results: Klebsiella was the most common bacteria among the cultured samples. The average length of hospitalization of patients with positive culture Covid-19 was 16.09 days. Antibiogram results showed that among gram-negative bacteria, the highest sensitivity is related to gentamicin, and the highest resistance is related to meropenem, and among gram-positive bacteria, the highest sensitivity is related to oxacillin and coamoxiclav, and the highest resistance is related to meropenem. Conclusion: Secondary infection caused by bacteria has increased the mortality rate of patients with Covid-19 and antibiotic resistance is high in bacteria isolated from patients with Covid-19.
